Habitat boundary

The following layers were considered in setting this boundary: * Geofabric stream and catchment network * SeaMap macrophyhytes etc * NSW estuaries * NSW estuaries and macrophytes (detail)

These were cropped to the bounding box of the biggest polygon surrounding Wallis Lake. Where sensible, they were subset to inlcude polygons whichonly covered plausible habitat. These can be viewed below:

Given the different layers give slightly different ideas about where habitat (i.e. water, mangroves, macrophytes, saltmarsh) exists, I simply tried to create a boundary which maximized these sets of extents. This included building a layer which first defined where land was within the estuary (in red below):
